Structural and Logical Design Solution Class Generalization With the Use of Design Procedures Representation Adapted Functionally 000_9.pdf

Design of modern products relating to different subject areas and consisting of a large number of components differs by the presence of the technical requirements to the entire product without separate requirements to its components. The design activity results include complete design documentation and product assembly 3D-model. The process of assembly 3D-model formation includes adding 3D-models of components and establishing conjugations between them. In order to construct, correct, and maintain (update or modify) a 3D-assembly, rebuilding should be provided. Typically, the process is carried out through manually handling of parts parameters and conjugations. That requires additional time and labor expenses. The authors propose the solution of the problem in establishing the structural and logical relationships between the components of the assembly 3D-model on the attribute level allowing to link the components and structural objects. Interrelations between the components allow not only to determine their location and link to each other operating with design parameter values but also to modify the design solution without violating its integrity that is not ensured by any modern cAD-system.

Computer-aided Design System of Structural and Functional Linguistic Models 38_12.pdf

The article describes a distributed design system, which is based on the multi-agent approach. A developed system architecture that describes the place and role of both system and its main subsystems in the distributed design process is presented. The interaction modes and the functionality of agents in the system are described. A structural and functional linguistic model generated from a designed device description by means of the VHDL language, one of the main objects with which agents and designers interact is considered. The main scenarios of interaction between the agents and a graph representation of such scenario are described. Basic technologies playing an important role in the process of the distributed-design system functioning are shown. A composition and a description of the internal and external dataware component functionality of the developed system are represented. A proposed solution in a form of a distributed design system is aimed at the quality improvement and the reduction of costs during a design solution creation.

Question-answer Modeling of the Operational Spacein Designing the Family of Automated Systems 36_13.pdf

For last 20 years, the successfulness of developing the software intensive systems (SIS) has been associated with a very low degree of a success (approximately 35% in accordance with universally recognized statistics of Standish Croup company), and it is an important reason for searching of new approaches to occupational activity in this subject area which enough fully reflects problems of occupational activity in human-computer environments. Negative influences of human factors (misunderstanding, ambiguity of reasoning and the others) are being recognized as basic reasons of unsuccessfulness in creating and using of SISs and automated systems (AS) as a subclass of SIS, and it inevitable concerns relations of the human with the software. A very important direction of an implementation and improvement of the human-computer activity is bound with discovering, representing and evolving an occupational experience. The special role of interactions with experience in human-computer environments is confirmed by active evolving of the subject area “empirical software engineering” in the frame of which the special kind of “metrology” is developed. This subject area is also bound with the creation and use of the Experience Bases and Experience Factories and with methods and means of “experimenting” in human-computer environments. Told above includes sufficient arguments to count the creation of innovative methods and means of conceptual experimenting in human-computer environments is topical.Formalization of conceptual experimenting is implemented with using a system of rules of the generated grammar which shall include the sets of rules specifying a reflection of all components of professional work onto a question-answer memory. A program realization of the instrumentally technological environment intended for conceptual experimenting, in the form of a program product which is demanded commercially and adjusted on a definite kind of occupational activity.

Communicative Maintenance of Designers’ Activity in Processes of Creating and Using an Experience Base 35_9.pdf

The paper presents a communicative maintenance of a designers’ activity in processes of creating and using an Experience Base of a design company that develops a family of automated systems. The experience base is intended for accumulating all kinds of company assets for their reuse in creating the next members of the family. All assets active as a typical solution is formed as a precedent’s model that opens an inclusion of the corresponding solution in the process of designing. Such models are bound with design decisions that can be useful in the subsequent development. For uniform representation of such models in the Experience Base, the typical scheme of precedents is specified. The scheme includes the statement of the corresponding task, a number of conceptual models and a pseudo-code program of the task decision Communicative maintenance serves to forming and checking the correctness of each component of each precedent’s model. The communicative maintenance is based on a set of communicative tasks the decisions of which are included in processes of designing. In a corporate network, the communicative maintenance is realized in two versions. Both versions are developed in an instrumental environment of a question-answer type. One of these versions is implemented by means of Web-programming. The corresponding toolkit provides registering of question-answer reasoning of designers solving the project tasks. Thus, specificity of communicative maintenance is defined with its orientation on precedents and the decision of communicative tasks in the specialized question-answer environment.

Cad, communication, precedent, experience base.
